Biokonserwatyzm i preferencja status quo

Bioconservative view holds that we should prevent dissemination of biomedical inteventions enhancing human capacities. One of arguments against this view shows that it is based on status quo bias which gives unjustified preference for actual state of affairs. According to this argument reasons against human enhancement are not conclusive. The aim of this article is to show the possibility of the interpretation of the bioconservative view, under which it is possible avoiding the status quo bias objection

Observables for General Relativity related to geometry

We present a new scheme of defining invariant observables for general relativistic systems. The scheme is based on the introduction of an observer which endowes the construction with a straightforward physical interpretation. The observables are invariant with respect to spatial diffeomorphisms which preserve the observer. The limited residual spatial gauge freedom is studied and fully understood. A full canonical analysis of the observables is presented: we analyze their variations, Poisson algebra and discuss their dynamics. Lastly, the observables are used to solve the vector constraint, which triggers a possible considerable reduction of the degrees of freedom of general relativistic theories.Comment: 33 pages, 1 figur

Addendum: Observables for General Relativity related to geometry

In this addendum we clarify a point which strengthens one of the results from [the original paper]. Namely, we show that the algebra of the observables $F(r,\theta)$ is yet simpler then it was described in [the original paper]. This is an important point, because with this simplification an important subalgebra becomes canonical, allowing for a natural reduction of the phase space.Comment: 4 page
